本地鏡像管理

• docker images: 列出本地鏡像；
• docker rmi：刪除本地鏡像；
• docker tag：標記本地鏡像；
• docker build：使用DockerFile創(chuàng)建鏡像；
• docker history：查看指定鏡像的創(chuàng)建歷史；
• docker save：將指定鏡像保存成tar歸檔文件；
• docker load：導入使用docker save命令導出的鏡像；
• docker import：從歸檔文件中創(chuàng)建鏡像；
• docker commit：從容器修改中創(chuàng)建新的鏡像；

列出本地鏡像

語法如下：

docker images [OPTIONS] [REPOSITORY[:TAG]]

Options:
  -a, --all             Show all images (default hides intermediate images(默認隱藏中間鏡像層))
      --digests         Show digests(顯示摘要信息)
  -f, --filter filter   Filter output based on conditions provided(顯示滿足條件的鏡像)
      --format string   Pretty-print images using a Go template
      --help            Print usage
      --no-trunc        Don't truncate output(顯示完整的鏡像信息)
  -q, --quiet           Only show numeric IDs

刪除本地鏡像

語法如下：

docker rmi [OPTIONS] IMAGE [IMAGE...]

Options:
  -f, --force      Force removal of the image(強制刪除鏡像)
      --no-prune   Do not delete untagged parents(不移除該鏡像的過程鏡像，默認移除)

例如：

# 刪除所有鏡像
docker rmi $(docker images -q)　

# 批量刪除無用鏡像
docker rmi $(docker images -f dangling=true)

標記本地鏡像

語法如下：

docker tag SOURCE_IMAGE[:TAG] TARGET_IMAGE[:TAG]

使用DockerFile創(chuàng)建鏡像

語法如下：

docker build [OPTIONS] PATH | URL | -

Options:
      --build-arg list             Set build-time variables (default [])
      --cache-from stringSlice     Images to consider as cache sources
      --cgroup-parent string       Optional parent cgroup for the container
      --compress                   Compress the build context using gzip
      --cpu-period int             Limit the CPU CFS (Completely Fair Scheduler) period
      --cpu-quota int              Limit the CPU CFS (Completely Fair Scheduler) quota
  -c, --cpu-shares int             CPU shares (relative weight)
      --cpuset-cpus string         CPUs in which to allow execution (0-3, 0,1)
      --cpuset-mems string         MEMs in which to allow execution (0-3, 0,1)
      --disable-content-trust      Skip image verification (default true)
  -f, --file string                Name of the Dockerfile (Default is 'PATH/Dockerfile')
      --force-rm                   Always remove intermediate containers
      --help                       Print usage
      --isolation string           Container isolation technology
      --label list                 Set metadata for an image (default [])
  -m, --memory string              Memory limit
      --memory-swap string         Swap limit equal to memory plus swap: '-1' to enable unlimited swap
      --network string             Set the networking mode for the RUN instructions during build (default "default")
      --no-cache                   Do not use cache when building the image
      --pull                       Always attempt to pull a newer version of the image
  -q, --quiet                      Suppress the build output and print image ID on success
      --rm                         Remove intermediate containers after a successful build (default true)
      --security-opt stringSlice   Security options
      --shm-size string            Size of /dev/shm, default value is 64MB
  -t, --tag list                   Name and optionally a tag in the 'name:tag' format (default [])
      --ulimit ulimit              Ulimit options (default [])

查看指定鏡像的創(chuàng)建歷史

語法如下：

docker history [OPTIONS] IMAGE

Options:
  -H, --human      Print sizes and dates in human readable format (default true)
      --no-trunc   Don't truncate output
  -q, --quiet      Only show numeric IDs

鏡像保存

語法如下：
